SmartMoms in WIC: A Smartphone Intervention for WIC Mothers to Improve Nutrition and Weight Gain During Pregnancy

The study will test the effectiveness of a smartphone-based behavior modification program adapted for use in Women, Infants, and Children program in a state-wide, randomized controlled trial in 432 low-income women enrolled in the Louisiana Women, Infants, and Children program.

Detailed Description

The study is a multi-site randomized controlled trial, testing the effectiveness of the smartphone-based behavior modification program in pregnant women within the Louisiana Women, Infants, and Children program. Equal number of participants will be randomized to either the intervention or the control. Although the intervention itself lasts 24 weeks (only during pregnancy), women will be enrolled in this study for approximately 18 months, from the 10-16th week of pregnancy until 12 month postpartum follow-up. Study outcomes will be assessed at three visits during pregnancy (early, mid, and late,) and three visits postpartum (1, 6, and 12 months).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: WIC Nutrition
Participants will receive weight management advice and care through the standard Women, Infants, and Children program. They will also receive weekly health information related to pregnancy, birth, and infant health through a closed Facebook group.
Experimental: Healthy Beginnings
Participants will receive the SmartMoms smartphone application, a wireless connected scale, and a Fitbit. The Healthy Beginnings program includes a 24 week intensive behavior modification program that targets healthy gestational weight gain through self-monitoring of weight and activity data, automated prescriptive feedback from the SmartMoms smartphone application, personalized feedback from counselors, and evidence-based behavioral intervention delivered throughout pregnancy.
